' Ciazenef the United swag, of the city vof Ltcp wall closed and secured.

Marseilles, in the county of Lasalle land State of Illinois, have invented certain new and useful Improvements in' Containers; and I do hereby declare that the following' is a full, clear, and exact description thereof, reference being had.to the accom anying drawings, and to the letters of re erence marked thereon, which form a part of this specification.

This invention relates to a novel paper box or container made from' stiii' or'heavy aper board, straw-board or the like materiali and designed more espnecially tobe used in place cfa wooden pac'ng boxtor containing a iilimber of packages of filled cartons and the The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

. In'the accompanying drawings: Figure 1 illustrates in perspective a View of the completed box.' Fig. 2 is a plan view showing the top of the box with the a s forming the l ig. 3 is a detail sectional View of the overla ping flaps taken upon line 3 3 of Fig. `2. .41g..4` illustrates in perspective a set up body ofthe box with one of thelaps in partially open position. Fig. 5 is a detail sectional View or' the overlapping flaps taken upon line 5'5 of lFig. 2. Fig. 6 is a perspective view illustrating a modified form of the completed box. Fio". 7 is a plan view of the box illustrated in'IPig. 6. Fig. 8 is a longitudinal sectional view taken upon line 8-8 of Fig. 7.

The body of a box or container embodyin my invention is of .tubular form and is pre erably made from an elongated sin le piece or blank which is bent into tubular iorm and the ends of which are secured to each other by suitable Afastening means. The tubular body :of 4thebox is shown as consistin0r of four connected side walls A, A1, A2, A3. aid walls 'are provided at their end margins with fiapsAj, A", A6, A7 which'are folded together to constitute an end 'wall. Said vflaps are of the saine widths as the side walls on which they are formed. The two opposite flaps A4,

A. on the side wallsA A2 constitute the inner flaps of the end wall. When the iaps are folded inwardly to formthe end wall of the box, said flaps A4 A are folded inside the Beps A A'r and in the same plane with each other. The other pair or 'outer 'flaps A AT are made in length somewhat greater than one-half the width of the end walls A A2, so that said iiaps Als AT overla each other at their margins when folde inwardly, as

clearly indicated in Fig. 2 and by the dotted lines in Fig. 4. Each p A AT is provided at the central part of its end margin with a notch forming a laterally .extending locking tongue, the tongue on the ap A5 being indicated by a, and that on the iiapv A7 by a1. Said tongues 'aol overhangthe notches by whichthe same are formed, and their inner marginal faces extend transversely of the ffla s or are substantially parallel with the en margins of said iaps, so that when the said tongues on the twolaps are interlocked with each other,'t.heir inner edges engage each lother in such manner as to positively hold or lock the iiaps from vmovement in a direction away from each other, as clearly indicated by the dotted lines in Fig. 2. When said aps A, A?, provided with notches and locki ing tongues made as described, are folded inwardly and interlocl'red with each other, the overlap ing parts of the flaps at the opposite side of t e notches will be reversely arranged. In other words, the marginal part of each flap at one side of the central notch therein will extend beneath, and the marginal part of the same flap a'tithe other side of the said notch will extend over, the corresponding marginal part of the other a Y When the container provided with flaps made as described is set up and closed by the folding inwardly of the flaps, the flaps are secured in their folded position by means of separate closing strips B, B of thin or 'iiexible paper which are secured by adhesive" material overt-he corners of the certaines at the junctions of the opposite walls A, A2,-

joints between the flaps except at the cen-l tral ,parts of the flaps A5, A7, 'where the overlapping parts of the said marginsare y held in close contact with each other by the side walls A and interlocking engagement of the tongues a and a1.

As clearly seen in Fig; 2, the side margins of the flaps A and A7' are cut away, conveniently on oblique lines, so as to make the said ap's slightly narrower than the body of the container. This construction has the advanta e of preventing ftea-ring or rupture of the closing stri s B, B by lateral movement of the side ec ges of the said iaps rela tive to the walls A and A2,v such as might occur through pressure being brought on diagonally opposite corners of the body of the container, in a manner to distort the same from its rectangular shape. f If the side edges of the said flaps were Hush with the A2, any lateral movement of the ends of the fiaps, produced by distortion of the box, would vcarry one of the vsaid side edges outside of the plane of the 'adjacent box wall,

and thereby produce a shearing action which would tear or rupture the closing strip, but when the side margins are cut away, of the covering strips will permit a slight lateral movement of the flaps without injury to or tearing of the same, inasmuch as no shearing action can, in that case, result.

The cutting away of the side margins of the said iaps A5, AT also has the advantage of eliminating the right angled edges at the corners oiE the containers over which the closing strips are applied and thereby lessening the liability ofthe said strips being torn or ruptured by abrasion in handling. As clearly shown in Fi the said flaps A5 an -Aare offset inwardly from the planes of the end walls of the box, forming at the said corners blunted edges over which the closing rounded form.

In addition to the use of the closing strips, for securing the llaps together, adhesive material may 'e applied to the flaps A5, A?, as .indicated by the reference letters a2, a2 in Fig. 4, in which case a stronger end will be formed on the box than when the closing strips alone are used.

Instead of using the separate closing strips applied one to each end of the top of the box a single piece of paper B1, as shown in Figs'. 6, 7 and 8, which is long enough to extend across the top of the box and downwardly on the adjacent side walls, may be employed. A. single closing strip thus made and applied will serre to completely seal thev end wall of the container and has the additional,advantage in that it can be applied in one operation instead of two as in thelcase ofthe two closing strips. The end portion of the strip B1 will correspondlto the strips B, B. Such a strip B1 may be made narrower or wider than shown in the drawings, B, B

can be made longer or shorter than "purpose for which they are as illustrated, the flexibility 2, the ond margins of rips extend in and the strips-A said outer i'iaps being accomplish .the employed. and unyielding those illustrated and still By reason of the stil character of the sheet material of which the` container is made, the a s A y tend to when folded inwardly, and

spring apart when the flaps are secured onlyby adhesive material applied thereto, it becomes for that reason necessary to retain the flaps in contactwith each other by pressure applied thereto for a period of insure the setting or hardening of the adhesive material. Maintaining the apslunder pressure during the packing of `commodlties is not only va troublesome operation but one which consumes considerable time. When thin and Aflexible paper closing strips are emthe same will immediately -v container, when ployed, however, adhere to the parts of the pressed into intimate Contact with the same, so .that by the use of such strips the operation of closing the container may be quickly peri ned by unskilled persons, with contime long enough toV sequent saving of time and expense, whether the flaps be themselves secured together by adhesive material or not.

l claim as my invention l. A box of sheet material having connected side walls and an end wall, said end wall consisting of two opposite inner flaps which are folded inwardly into the saine plane and two oppositev outer flaps which are folded inwardly against the inner flaps, which overlap at their meeting margins, and each of which has at its margin a notch forming a laterally extending tongue, the tongues on the two outer flaps extending in opposite directions and nterlockedv with each other, and the marginal part of each outer iiap, at one side of thenotch therein, extending beneath, and at thev other side of said notch extending over the marginal part of' the vouter liep, and closing strips of thin and flexible material applied by adhesive :material tothe outer aps and to the side walls of the box adjacent 'to the side margins of said outer iaps. 2. A box of sheet material. having connected walls andan end wall, said end wall `consisting of two opposite inner flaps which are folded inwardly into the saine plane and two opposite outer llaps which are folded 'inwardly against the inner flaps which overlap each other at theirmeeting n1argins, a`id each of which has in its inargin not-ch` forming a-laterallyf extending tongue," the tongues on the ytwonouter flaps extending in opposite directions :and inter-' lockedfwith each other, and the marginal' part of each outer flap atone side' ofi the notch therein extending. beneath, other marginal part oi' the flaps and to Veach other y andfat the? side of said notch extending overA the f other outer tlalgwand secured to the inner in their overlapping portions, by adhesive material, and closing strips of thin and'exble material applied by adhesive mate-rial tu chey outer flaps and to the side Walls of the box adjacent in the side margins of said nuter iaps.

In testlmony, that l claim the foregoing as my invention I aix my signature in presof two n-'itnesssj a'his 1st day of July H08.
